Vista and Visual Studio 2003 – Not Supported

Now that Vista has gone RTM, lots of us are trying to decide when to upgrade. Here is something I have not seen much mention of:

Visual Studio 2003 is not supported in Vista.

This is going to hold back adoption on my work machine. I’m a consultant, I have to do work on whatever platform the client is using, which unfortunately is VS 2003 sometimes. Is VS 2003 going to be relegated to life in a virtual machine from now on?
